In electronic packaging, carrier tapes, and pallets, static electricity is an “invisible killer” of precision components. HIPS conductive masterbatch PS0603C, specifically designed for antistatic HIPS three-layer co-extruded sheets, is a key functional material for solving static electricity hazards and balancing performance and processability.
What is HIPS Conductive Masterbatch PS0603C?
HIPS conductive masterbatch PS0603C is a black functional masterbatch made from HIPS (high-impact polystyrene) as a carrier, using Cabot high-performance conductive carbon black as the conductive core, compounded with SEBS elastomer and special additives, through high-temperature melting, precision mixing, and granulation.
- Core Applications: Production of antistatic HIPS three-layer co-extruded sheets, widely used in electronic component carrier tapes, packaging pallets, antistatic turnover boxes, etc.
- Addition Ratio: Adding approximately 28% to the HIPS substrate is sufficient to stably impart antistatic properties to the sheet.
- Antistatic Effect: The surface resistivity of the formed sheet is stably controlled at 10⁵~10⁷Ω/sq, perfectly matching the antistatic standards of the electronics industry.
- Formulation Advantages: Utilizing Cabot carbon black, which boasts high conductivity and excellent dispersibility; combined with SEBS elastomer, it significantly enhances the toughness and impact resistance of HIPS sheets, solving the problems of brittleness and cracking inherent in traditional conductive masterbatches, while maintaining the fluidity of the substrate during processing.
Four Core Features of HIPS Conductive Masterbatch PS0603C
- No Crystal Points on the Surface, Excellent Appearance and Texture
Employing a multi-stage melt-shear coupled ultrasonic-assisted dispersion process, Cabot carbon black is uniformly dispersed in the HIPS carrier without agglomeration, completely avoiding problems such as crystal points, pitting, and color differences on the sheet surface. The formed sheet surface is smooth and even with consistent gloss, meeting the stringent appearance requirements of high-end electronic packaging.
- Stable Resistance and Long-Lasting Antistatic Performance
Leveraging the high conductivity and stable conductive network structure of Cabot carbon black, adding 28% results in a precise surface resistivity of 10⁵~10⁷ Ω/sq for the sheet, with minimal batch-to-batch variation. Unlike ordinary antistatic agents, HIPS conductive masterbatch PS0603C is permanently conductive, unaffected by environmental humidity and temperature, and will not fail due to surface wear or long-term use; its antistatic lifespan is consistent with the product.
- Low Dosage, Excellent Cost-Effectiveness
Compared to similar conductive masterbatches requiring 25%~30% addition to achieve the desired effect, HIPS conductive masterbatch PS0603C, thanks to the high conductivity of Cabot carbon black, only requires approximately 28% addition to achieve the ideal antistatic effect. This reduces carbon black usage, minimizes the impact on the mechanical properties of the HIPS substrate, effectively controls raw material costs, and enhances product competitiveness.
- Stable Performance and Strong Processing Adaptability
- Balanced Mechanical Properties: The SEBS toughening system significantly improves the impact strength and elongation at break of the sheet, while maintaining the original rigidity and toughness of HIPS. The finished product is resistant to bending and not prone to cracking.
- Excellent Processability: HIPS conductive masterbatch PS0603C has excellent compatibility with HIPS substrates, adaptable to various processes such as three-layer co-extrusion, extrusion thermoforming, and injection molding. It exhibits stable flowability, no exudation, and low die buildup during processing, resulting in high production efficiency.
- Good Batch Consistency: A strict production quality control system ensures that the carbon black content, dispersion, and conductivity of each batch of masterbatch are consistent, eliminating the need for frequent parameter adjustments in downstream production.
